Experience in developing a highly-portable TCP/IP stack (lwIP) that
works
also outside BSD/Unix/Linux environments: do not try to implement or
even
wrap around locking mechanisms.

I would strongly suggest instead of making the global (static) data
being
allocated on the caller's behalf, removing the thread-unsafety
altogether.

I am not sure what this would mean to the caller (maybe they cannot
share
font caches) but this is less of an issue.

Just my two cents,

Leon.
